The toString() method of java.lang.Class class is used to convert the instance of this Class to a string representation. This method returns the formed string representation.

Syntax:

Return Value: This method returns the String representation of this object.

Below programs demonstrate the toString() method.



Example 1:




// Java program to demonstrate toString() method
  
public class Test {
    public static void main(String[] args)
        throws ClassNotFoundException
    {
        // returns the Class object for the class
        // with the specified name
        Class c1 = Class.forName("java.lang.String");
  
        System.out.print("Class represented by c1: ");
  
        // toString method on c1
        System.out.println(c1.toString());
    }
}
Output:
Class represented by c1: class java.lang.String

Example 2:




// Java program to demonstrate toString() method
  
public class Test {
    public static void main(String[] args)
        throws ClassNotFoundException
    {
        // returns the Class object for the class
        // with the specified name
        Class c2 = int.class;
        Class c3 = void.class;
  
        System.out.print("Class represented by c2: ");
  
        // toString method on c2
        System.out.println(c2.toString());
  
        System.out.print("Class represented by c3: ");
  
        // toString method on c3
        System.out.println(c3.toString());
    }
}
Output:
Class represented by c2: int
Class represented by c3: void
